One day, the lost will be found
I think it's possible that in the confusion from hypoxia they were randomly swatting at buttons to make the noises stop. I remember on the Helios flight that the pilot got agitated and yelled at the air traffic control guy asking about the location of his something. They thought it was odd because he didn't answer their question and asked about something he should have known the location of.
Right.
So it's quite possible the controls were accidentally switched off due to confusion from hypoxia-if that's even what happened.
